Answer:
3C1 * 7C6 * 3C2 * 3C3
Step-by-step explanation:
Dado que solo tres saben cómo conducir, de estos tres uno estará en la posición de conducción, por lo tanto, el número de formas en que este conductor puede elegir entre estos tres es 3C1 * 7C6
Ahora, 2 de los conductores se sentarán en los asientos de los pasajeros junto con otros tres 3C2 * 3C3
Número total de oportunidades = 3C1 * 7C6 * 3C2 * 3C3
What is the slope of the line through the points (-2, -1) and (4, 3)?
Answer: [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Answer:
m=2/3
Step-by-step explanation:
Identify the coordinates (x₁,y₁) and (x₂,y₂) . ...
Input the values into the formula. (-2,-1) (4,3) the formula is (y1-y2)/(x1-x2)
Subtract the values in parentheses to get 4/6
Simplify the fraction to get the slope of 2/3

Step-by-step explanation:
Presale tickets (p) are each worth $7: represented in the equation as 7p.
Door tickets (d) are each worth $10: represented in the equation as 10d.
They sold 345 tickets, so p+d=345. They collected $2550, so 7p+10d=2550.
Final answer:
(3) [tex]\left \{ {{7p+10d=2550} \atop {p+d=345}} \right.[/tex]
A submarine begins its descent from the surface of the water and dives 20 feet for each minute. What would be the depth of the submarine after 2/3 hours?
Answer:
Distance = speed * time
Convert feet to meter (C units) = about 6
Convert hours to second (C units) = about 2399
Distance = 6 * 2399
= 1439 meters
4721 foot
Write the slope-intercept form of the equation for the line

Solve for x:−2(x+9)=−1(x+−1)+2
Answer:
A
Step-by-step explanation:
expanding the bracket, we would have
-2x -18 = -x+1+2
-2x+x= 3 +18
-x=21
x=-21
Answer:
A
Step-by-step explanation:
−2(x+9)=−1(x+−1)+2
Use distributive property
-2x - 18 = -1x + 1 +2
-2x - 18 = -1x + 3
+18 +18
-2x = -1x +21
+1x +1x
___________
-x = 21
we need to have a positive x so multiply x by -1. -x times -1 = x
What we do on the left side has to happen to the right side too
So, 21 times -1 = -21
Therefore, x = -21
Hope this helps :)

Select the correct answer.
Martin runs 100 meters in 15 seconds. What is the equation for d, the distance in meters that Martin covers per second?
A.
15 + d = 100
B.
100 + d = 15
C.
d × 15 = 100
D.
d × 100 = 15
Answer:
c
Step-by-step explanation:
We are dividind how 100 can fit in 15 seconds
which is 100 /15
therefore when C when u tak it to the other side it divides 100 in 15
d×15=100
d=100/15

Let x be the hottest temperature.
Equation: x - (-35.67) = 148.98
So,
x - (-35.67) = 148.98
=> x + 35.67 = 148.98
=> x = 148.98 - 35.67
=> x = 113.31

solve the simultaneous linear algebra quadratic equation 2x-y=8 3x-y=17
Answer:
2x-y=8
(3x-y=17)*_1
2x-y=8
-3x+y=-17
#-x=-9, x=9 & y=-10
Answer:
x = 9 and y = 10
Step-by-step explanation:
Subtract the second equation from 1 as in doing so the y will get cancelled as they are of the opposite sign.
2x - y = 8
-3x + y = -17
-----------------
- x = - 9
Therefore,
x = 9
Now we will add the value of x to any of the equation from the question.
2x - y = 8
2(9) - y = 8
18 - y = 8
Therefore,
y = 10

O y = -3x - 2
O y = -3x + 2
O y = 3x + 2
O y = 3x - 2
⊹˚ʚ ❑Answer︰The slope is 3!
⊹˚ʚ ❑Explanation︰use the formula y2-y1 over x2-x1
✎Daily reminder: make sure to eat food and stay hydrated, have a good day :D
Answer:
y = 3x - 2.
Step-by-step explanation:
The slope of the line (m) = (10-4)/(4-2)
= 3.
y - y1 = m(x - x1)
y - 10 = 3(x - 4)
y = 3x - 12 + 10
y = 3x - 2.

Answer: [tex]2\sqrt{2}[/tex]
=====================================
Explanation:
Let's say we replace every copy of [tex]\sqrt{2}[/tex] with x
Doing so means we have the expression 5x-3x. That simplifies to 2x.
The last thing to do is replace the x with [tex]\sqrt{2}[/tex] and that's how we end up with [tex]2\sqrt{2}[/tex] as the final answer.
----------
In short: we subtract the numbers out front, and then tack on a root 2 at the end.
As another example, [tex]19\sqrt{2}-11\sqrt{2} = (19-11)\sqrt{2} = 8\sqrt{2}[/tex]
This is basically the same as saying 19x-11x = (19-11)x = 8x where [tex]x = \sqrt{2}[/tex]

The value of the unknown number is 5. The correct option is B.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that 3 is more than 3 times a number is equal to 12 less than 6 times the number.
The value of the unknown number will be calculated as,
3n + 3 = 6n - 12
6n - 3n = 12 + 3
3n = 15
n = 5
